The report presents the results of the survey on alcohol and drug use conducted in 1991 by Santé Québec. This survey is part of the Enquête québécoise sur les facteurs associés au sida et aux autres MTS carried out among the population aged 15-29.

This report documents the situation of alcohol and drug use in this age group, then looks at the interrelationships between alcohol and drug use and the sexual behaviours of young Quebecers (sexual experiences, sexual partners, risk behaviours).

The target population of the survey is the non-institutionalized Québec population (excluding northern regions) aged 15 to 29. Telephone interviews were conducted with 3,000 people.
